FOXBORO >> Mandatory minicamp is when contract holdouts become official across the NFL.

The Patriots don’t have any players unhappy enough with their contracts to skip mandatory minicamp, but the front office is at least monitoring other situations across the league.

“I think that we have to,” head coach Mike Vrabel said Tuesday. “It would go for the ability to acquire good players, good people that feel like they can help us at any position. I don’t know what those situations are throughout the league, but I’m all for trying to make the roster better any chance that we can.”

Two premier pass rushers, the Bengals’ Trey Hendrickson and the Steelers’ T.J. Watt, and Commanders wide receiver Terry McLaurin are skipping mandatory minicamp as they seek new contracts. Dolphins tight end Jonnu Smith and cornerback Jalen Ramsey also aren’t in attendance for mandatory minicamp.

The Patriots still have the highest salary cap space in the NFL at $60,435,177, per OverTheCap.com. Vrabel wasn’t ruling out the idea of seeking help across the roster.

“I think that should go for every position on a roster,” Vrabel said when asked if the team would still be interested in adding competition or depth. “We would always want to do that, I think. Trying to always continually make the roster more competitive and trying to find everybody that can continually help us from now until the end of the season. I think that just has to go on. That has to happen. Whether that does or not, I don’t know. It’s not going to keep us from looking, trying to bring up ideas or players, or how we acquire players between now and the end of the season.”

The Patriots added edge defenders Harold Landry and K’Lavon Chaisson, wide receiver Stefon Diggs and cornerback Carlton Davis this offseason, and they re-signed tight end Austin Hooper, but there’s always more room for talented players on the roster, especially if Watt, Hendrickson, McLaurin or Ramsey become realistic possibilities. Vrabel could certainly use more help at wide receiver and on the edge.

The Patriots have additional fourth-, sixth- and seventh-round picks in the 2026 NFL Draft via trades.

If the Patriots don’t use their cap space, then it will roll over into next season when they might be set up to be more competitive. With their current roster, their current win total over/under is 8.5 on sportsbooks.

Veteran OL retires

The Patriots placed offensive lineman Wes Schweitzer on the reserve/retired list Tuesday.

Schweitzer, 31, signed as a free agent this offseason after prior stints with the Jets, Commanders and Falcons. Over nine seasons, he logged 62 starts in 90 regular-season game appearances. This spring, he split the top practice reps at left guard with former first-round pick Cole Strange, who took virtually all of them during the Patriots’ final minicamp practice Tuesday.

Schweitzer’s retirement dents the depth at an already questionable position for the Patriots. Over the offseason, the front office restocked one of the NFL’s worst offensive lines with right tackle Morgan Moses, center Garrett Bradbury and first-round rookie left tackle Will Campbell.

But between them, the Pats’ guard depth is down to Strange, projected starting right guard Mike Onwenu, Sidy Sow, 2024 fourth-round pick Layden Robinson, Tyrese Robinson and 2024 third-round pick Caedan Wallace, a career offensive tackle. Undrafted rookie Jack Conley, a Boston College product, is also in the mix.

Training camp dates

The Patriots will open their 2025 training camp on July 23, the team announced Tuesday.

The Patriots will open 12 practices to the public this summer outside Gillette Stadium. All outdoor practices will begin at 10:15 a.m. Fan admission and parking are free.

After players report for physicals and conditioning tests on July 22, practices will be held July 23-26, July 28-31, Aug. 3-6 and Aug. 10. The Patriots are scheduled to host the Commanders for a joint practice on Aug. 6, then a preseason game in Gillette Stadium on Aug. 8. Per the league’s CBA, the team cannot practice in pads until July 28.

In a press release, the Patriots encouraged visiting fans to check their website and app for updates. All training camp dates and times are subject to change.

DC Williams back ‘soon’

Patriots defensive coordinator Terrell Williams remained absent for the team’s two minicamp practices this week.

But following Vrabel’s comments before Tuesday’s indoor session, Williams might return next month for training camp.

“(He’s) doing well. He’ll be here soon and (he’s) excited about that,” Vrabel said, “so I think everybody’s looking forward to that.”

Williams, 50, has been away from the team for months as he recovers from an undisclosed medical issue. The ex-Titans and Lions defensive line coach said he endured a “traumatic” event in his lone press conference of the offseason in May. Williams has been in regular contact with players and coaches via video conference, while inside linebackers coach Zak Kuhr has handled the defensive coordinator duties on an interim basis.

“I came back home here to Detroit, for spring break, and had a little medical scare. I mean, it wasn’t a little medical scare. It was a medical scare,” Williams said last month. “Since then, per doctor’s orders, I’ve kind of stayed here, in Detroit, and been handling that.”
